She’s clearly having fun, running around in circles, chewing sticks, and finding and eating cat poop. And I don’t want to discourage her from having fun when I take her outside (except for the cat poop thing – that needs to stop).
But she seems to have the idea that jumping up and biting my wrists or my ankles is a fun game that we both enjoy, and she seems to be getting more agressive about it.
Stop playing as soon as it happens. Wait 10-15 mins before going again.
To add onto this use reinforcing language. Soon they’ll start to react to the word so you will continue playing.
